We are treating my pug (2,5 year old) from pneumonia one week with antibiotics and diuretics but today on xray showed suspected not defined tumor mass. What to do next to have the right diagnoze? Thank you

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear that Kan is having a problem. This could be tricky but the next step would be a CT scan or MRI Scan. Not sure if ultrasound would be helpful but maybe. A fine needle biopsy or aspirate of the mass or a surgical biopsy would hopefully be able to obtain some tissue from the mass to determine what it is. I cannot make out much on the xrays due to the quality over the internet. Possibilities of a mass always fall into some broad categories including an abscess (pus filled pocket from infection), a granuloma or collection of inflammatory cells), a seroma of fluid fulled sac, a hematoma or pocket of blood, or a tumor which could be benign (not cancer) or malignant (cancer). Kan is very young to have a tumor but it must be on the differential list. What else could it be? A very congested lung lobe from multiple things, a lung lobe torsion where a lobe of the lung turns on it's axis and is out of place, an area of calcification, etc. I hope this helps and I hope Kan does really well for you. I'm hoping for the best for you two.

    I am sorry to hear that! It is hard to tell from the pictures, but I imagine your vet would want to re-check the x-rays and/or consider an ultrasound or visit to a specialist next. If he is on antibiotics and diuretics, I would imagine they are hoping for an improvement on the meds! I hope this helps and Kan is much better soon!
